Solution Overview

Problem

Existing battery packs for heating elements either require batteries to be removed for charging, making them inconvenient for replacement or upgrading, or are designed as single units where the entire pack must be replaced if the battery is defective, preventing retrofitting with larger batteries.

Innovation Solution

A battery pack design with separate housing parts for the battery unit and control unit, featuring releasable connections and positive locking elements, allowing for easy replacement and upgrade of batteries without requiring the entire pack to be replaced.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the battery pack is designed as a single integrated unit, then the structure is simple and convenient, but the battery cannot be replaced or upgraded

Engineering Contradiction:
Improveconvenience of battery replacementVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The battery pack is divided into two separate housing parts: a first housing part for accommodating the battery and a second housing part for accommodating the control unit. These parts are detachably connected, allowing the battery to be replaced independently while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the battery pack is designed with detachable housing parts, then battery replacement is enabled, but the connection reliability between parts may be compromised

Engineering Contradiction:
Improvebattery replaceabilityVSAvoidconnection reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

Locking elements are pre-provided on the housing parts that automatically engage when the parts are connected. This preliminary provision of locking mechanisms ensures reliable connection without requiring additional steps or complex assembly procedures during battery replacement.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The housing parts are designed with complementary geometric features (protrusions and recesses) that guide precise alignment and engagement. This geometric design ensures that the connection between detachable parts is both easy to make and reliably secure.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Ease of operation

If standard rechargeable batteries are used in a housing with easy replacement design, then battery replacement is simple, but the batteries must be removed for charging

Engineering Contradiction:
Improvebattery replacement simplicityVSAvoidcharging convenience
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

By separating the battery housing from the control unit housing with a detachable connection, the design enables both easy battery replacement and the option to charge batteries externally. Users can remove batteries for charging without compromising the simplicity of the replacement process.

Inventive Principle:
Principle #1Segmentation
